CHARLES It. KLINE, OF READING, PENNSYLVANIA.

COMBINATION BOILER.

Application filed September To all whom it may concern.

Be it known that 1, CHARLES R. KLrNn, a citizen of the United States,residing at Reading, in the county of Berks and State of Pennsylvania,have invented certain new and useful Improvements in CombinationBoilers, of which the following is a specification.

My invention relates more particularly to boilers adapted for heatingresidences or like purposes, my main object being to provide for theconvenient and economical use of such boilers in accord with the greatlyvarying needs incident to variations in weather and other conditions.

The invention consists essentially in CO1 i bining with an ordinaryfiregrate boiler, 21 separately formed built-in section provided with afluidfuel burner and conduits and forming a separate combustion chamberarranged in communication with the same passage-ways through which thesolid-fuel products of combustion are discharged; so that saidfluid-fuel sect-ion may be readily and effectively employed either aloneto produce the relatively small amount of heat required for distributionin moderately cold or damp weather, or to supplement the solid fuel heatproduction when called for; as fully described in connection with theaccompanying drawings and specifically pointed out in the claims.

The drawing illustrates the application of my invention to a known typeof boiler, in a. simple manner adapted to make clear the essentialfeatures of the invention; Fig. 1 showing a sectional view of myfluid-fuel section in connection with the adjacent parts of a sectionalboiler and with a partial front view of the latter; and Fig. 2 showing asectional view on the line 2-2 of Fig. 1

The known type of boiler indicated made up of a series of connectedwater-coin taining sections 5, 5, 5, forming in combination with anash-pit base portion provided with door fronts 7 and 8, a suitablesolidfuel combustion chamber, with connnunicating passage-ways, as 9 and10, through the connected water-containing sections for dis charging theproducts of combustion. specifically indicated, these sections form aso-called side-feed boiler having a relatively wide fuel and combustionchamber with two solid-fuel firin doors 11 and ash-pit doors 12; and myseparately operative fluid-fuel section 20 is shown as located midwaybe- 9,1920. Serial No. 409,079.

tween these two firing doors, and arranged in communication with thesections 5, 5, on each side thereof.

My special section 20, as shown, is made to correspond in general formwith the cooperating ordinary water containing sections 5. but providesin itself a combustion chamber 21 separated from the adjacent solid-fuelcombustion chambers by spacedapart water walls 22; said chamber 21 beingin communication above with the passageway 9, through which the productsof combustion from chamber 21 are also discharged intothechimney-connected passage-way 10, and the water-containing spacebeing in communication withtha't of the sections 5 as usual. The section20 is carried upon integrally formed wall or partition plates 24;, 241-,as indicated, which form a separate chamber 25 on the level of theadjacent ashpit chambers 27, and below the water-wall bottom 26 of thecombustion chamber 21. Through the front wall 28 of this lower chamber25, which may be provided with a doored aperture 84, extends a conduit30 for the fluid-fuel, liquid or gass, to be used in the combustionchamber 21; which conduit passes through the bottom 26 and is connectedto a suitable burner 31 in the chamber 21; air passages 32 to the latterbeing also provided as indicated. A suitable opening is provided foraccess to the chamber 21, through the front wall thereof, to which adoor may be insulatingly applied as shown in my Patent No. 1,319,096issued Oct. 21, 1919.

In operating my improved boiler all the products of coml'mstion, whetherfrom solid or fluid fuel employed, pass through the section passage-ways9 and 10, to the chimney; but either the solid fuel or the fluid fuelmay be used independently, or both may be used together, as weather orother conditions may make desirable; the fluid fuel being veryconveniently, satisfactorily, and economically employed alone during theearly and late months of the cold season 1' occasional damp weather, andserving to readily supplement the usual solid-fuel heat broduct-ion inextreme weather. The application of the invention involves comparativelyinexpensive changes in constructions heretofore employed, and theshowing specifically set forth may be readily modified to suit desiredpatterns and arrangements.

It will be understood that the coal heated I water holding sections 5are connected to each other by the nipples 35, and that the gas heatedwater holding section 21 is connected to the contiguous coal heatedsections 5 by the nipples 36, so that a free and unimpeded watercirculation is permitted, the inlet and outlets for the sectional boilerbeing of the usual character and requiring no further description. Theback flue 10 of the gas heated section 20 may be connected with thefiues' 9 in any suitable manner as by the flue 37, said flue 10 having aconnection or exit to a chimney (not shown) as hereinbefore referred to.

What I claim is:

1. In a device of-the character stated, a plurality of water holdingsections, provided with transveise flues and communicating waterpassages, and a grate for the reception of solid fuel, in combinationwith a water holding section adapted to be heated by gas, said lattersection having a water connection to said other sections, and a flue incommunication with said transverse fiues, a gas burner located in thelower portion of said gas heated section, upright water j acketed wallsin said gas heated section located on each side of said gas burner, anda support for said gas burner having vertically connection to the othersections and an outlet flue in communication with said transverse flues,upright bottom walls upon which said gas heated section is supportedforming a lower chamber, upright water 1' acketed walls for said gasheated section supportedupon said bottom walls and having a combustionchamber formed therebetween, a gas burner positioned in the lowerportion of said combustion chamber between said water jacketed walls,and ports in proximity to said gas burner leading from said bottomchamher to said combustion chamber for conveying air into the latterfrom said bottom chamber.

In testimony whereof I affix my signature.

CHARLES R. KLINE.
